SPECIFICATION forming part of Letters Patent No. 776,592, dated December 6, 1904. Application ilcd November 8,1902. Serial No. 130,520. (No model.)

l'o (tu wle/mt it T11/ty concern:

Be it known that I, H nnnnn'r H. HULL, a citizen of the United States of America, and a resident of Cleveland, county of Cuyahoga, and

State of Ohio, have invented certain new and useful Improvements in VViring-lvlachineaof which the following; is a specification.

My invention relates generally to wiringmachines, and has more particularly reference Io to a machine for introducing a wire inside of the covers ofa packing vessel, such as is shown and described in Letters Patent No. 636,339. granted to me on the 7th of November, 1899, and is, furthermore, an improvement upon i 5 Patents N os. 588,749 and 634,112, heretofore granted to me.

l shall describe a wiring-machine embodying my invention and afterward point out the novel features in the claims.

`2o The cover or other article to be wired is usually in the form of a disk-shaped blank having a dependent surrounding edge or brim, inside of which latter the wire is introduced and attached by curling the said brim ove-r it. ln 2 5 order, however, to afford a means whereby the cover can be ripped off and removed from the body of the can to which it has been soldered, an excess of wire has to be provided, so that one end of same will project outside 3o of the said cover.

The main object of my invention is to produce a machine which will automatically provide the blanks with a wire in the most efficient and inexpensive manner. 1n carrying 3 5 out this object my invention comprises a plurality of dies (in this instance four) adapted to act successively upon a blank to accomplish the desired result and supplementary devices, notably a special construction of wire-feed 4o mechanism and a peculiar conveyor for shifting the blanks from one die to another and for progressing them through the machine. The lirst die is provided with a mechanism for partially curling the brim or dependent surrounding edge, so as to subsequently facilitate the complete curling of the said brim over the wire, and comprises an outer stationary ring or member having an annular ledge,

a vertically-movable member adapted to hold the upper portion of the dependent edge of 5o the'cover rigid against the inside of the stationary ring, and an inner expansible ring having an annular flange for pinching the lower portion of the brim of the cover and for allowing the lowermost portion of same 5 5 to be partially curled by the annular ledge of the stationary member. The second die is provided with an outer stationary member or ring and an inner horizontally-movable member. Adjacent to the said die are located two 6o parallel rock-shafts operated in unison, one of which carries a cutting device and the other of which has means for moving the movable member of the die against the stationary member of same in the direction of the cutting device, so as to pinch the blank or cover while the cutter is acting upon it. The third die is adapted to receive an excess of wire and to have part of said wire pulled out again and eut off from the continuous strand of wire be- 7o fore the blank or cover comes into position on the said die and to curl the brim of the said blank over the wire. To this end it comprises an intermediate member or ring havingl a circumferential depression, an outer verticallymovable member having' an inside peripheral surface and a circumferential ledge, the latter being substantially coincident with but not projecting over the circumferential depression of the stationary member, ,and an inner ex- 8o pansible member. The fourth die is merely a mechanism for bending the excess of wire which projects outside of' the blank up against the outside of the brim of the said blank.

The Wire-feed mechanism comprises two rolls adapted to receive an intermittent progressive motion to feed the wire and consists,

further, of a retractor vmechanism independent of the two rolls for pulling' part of the wire fed into the third die out again in order 9o to tighten the said wire around an inner expansible member or ri ng, so as to move it into the circumferential depression of the intermediate member. In connection with the wire-feed mechanism is also a safety-stop operated by the second die, by means of which no wire will be fed when by any accident there is no blank to receive it, thereby preventing the mechanism from becoming tangled up by the wire.

rl`he conveyer comprises, broadly, two parallel rock-shafts carrying members for progressing the covers through the machine by having a lengthwise or longitudinal movement imparted to them, the said members, however, rocking with the rock-shafts toward and away from each other, so as to seize and release the covers at the proper moment. The arrangement of the parts is such that the members are moved toward each other to seize the covers and then longitudinally in one direction, then out again or away from each other, and then back while in their outermost position longitudinally in the opposite direction.

My invention further comprises the combination and arrangement of parts and other features of construction, as will more fully hereinafter appear.

The blanks are fed to a continuously-revolving dial, which brings them into alinement with the conveyer and into the path of progression of the machine. Here they are taken singly and passed to the first die, which starts the inward curling of the lower edge of the brim just slightly to facilitate the subsequent complete inward curling of thebrim over the wire. rlhe blank is then progressed to the second die, which cuts two openings in the brim to allow the introduction of the wire in the proper manner and to allow the excess of wire to project out through one of the said openings. Incidentally a key impression is stamped in the upper surface of the blank. The blank now advances to the third or wiring die, into which the wire is introduced, an excess of wire being fed so as to allow the said wire to be tightened around and under the inner member or expansible ring into the circumferential depression of the intermediate member and so as to allow a portion of the same to project out through one of the openings aforesaid. lf there is no blank in the second die, the safety-stop will prevent the introduction of wire into the third die. The blank is then carried to the fourth die to bend the excess of wire up against the outside of the brim. The further progress of the blank moves it out of the machine.

In the accompanying drawings I have embodied myinvention in a suitable form. The

construction and arrangements of the parts, however, so far as the broad claims are concerned, can be widely varied, although the special structure shown involvesin itself new and valuable features of construction.

Similar letters of reference indicate corresponding parts in the dierent views.

A denotes a framework of any suitable construction, supporting the various parts and mechanisms of the machine. ln front are mounted the four dies B, C, D, and E, all located in alinement with each other and central of the path of progression of the blank through the machine. In proper relation to these are mounted in the head A' the four punches B', C', D', and E'.

F is the main shaft, carrying the pulleys f' and f2, from which motion is derived, and the pinion f3, meshing with the spur-gear g'of the cam-shaft Gr, mounted in suitable bearings in the rear of the machine.

The construction of the punches B', C', D', and E' need not be described in detail, as all the operating mechanisms peculiar to my invention are located in the dies. Sufliee it to say that they are operated in the guide A of the head A' and are actuated by the eccentricstraps g2 and g3 of the cam-shaft G through the levers c', a2, and L3 in a well-known manner, one set of levers being provided on each side of the machine.

H is a continuously-revolving blank-feeding dial, and I the wire-feed mechanism.

J is a conveyer for the blanks.

M is a reel of wire for the wire-feed mechanism.

IOO

The dial H revolves continually, it being driven from the pulley ,f/i by means of the belt passing over the idlers /zfi and lt to the pulley tl, mounted on the shaft it, carrying the dial H.v The said dial is further provided with a stationary feed-table lt, from which the blanks are fed, and with a stationary side -wall /t7 and center guide lt, which narrows down the space in which the blanks travel adjacent to the point where the dies are located, so that one blank is fed in at a time.

rlhe conveyer J is composed of two parallel rock-shafts j and f2, which carry two series of opposed grip pingl portions]3 and y, located in the saine horizontal plane, each series having in this instance live members, located in the same horizontal plane. These gripljiing portions are formed so as to properly grip the blank and preferably inu the shape of a V, as shown, and are usually provided with su pporting-ledges, as f5. These gripping portions are net mounted directly on the rockshafts j and f2, but are pivoted on the sleeves j, which are mounted fast on the rock-shafts by means of feathered keys j? in a well-known manner, so as to be capable of longitudinal reciprocating movement, which is imparted to lboth in unison by means of the cam G', lever jx, connection f), and cross-piecey'l", engaging with the flanges j of the grooves jl, one on each sleevey'. 'lhe spring jl is for the purpose of facilitating the return movement of the said sleeve j. The sleeves j, with gripping portions jg and jf, also partake of the rocking motion by reason of the feathered keys f7, which is imparted to the rock-shafts frand ,7'2 by means of the cam G2 and spring 71", the said spring normally holding the opposed gripping portions in contact with the blank, while the cam rocks the shafts outward by means of the lever ju, bell-crank jl, connecting-rod jl?, and crank j, which rock both shafts simultaneously, moving' the gripping portions toward and away from each other. The spring 7'1" helps to push the opposed gripping' portions away from each other. The parts are so arranged and timed that the gripping portions 7'3 and j are moved toward each other to grip the blank, then in a longitudinal direction to shift the blank held between each opposed pair of gripping` portions from one die to another, then they are rocked away from each other, leaving the blank on the said die, and linally return in a longitudinal direction, after which they are moved toward each other to seize the next blank. Five pairs of opposed gripping portions are shownw-that is, one more pair than the number of dies.

f: and /i are two stops Vto prevent the dial from feeding the blanks too fast or irregularly to the conveyer, both mounted on the spindle K. The stop 1 is normally held down by means of the springl a and is lifted up by the strip of bent metal lv, carried by the conveyer. The stop J, is held down by its own weight normally and is provided with an arm Zi', with which engages the arm j of the conveyer J to lift the said stop up when the opposed griiiiping portions move toward each other.

Each die is provided with aknock-out pad, resiiectively d, (Z', and J, which serves to receive the blank from the conveyer and to support it until the punch moves the blank down into the die and also to knock it out of the die again and to lift it up into a position where the conveyor can seize it. Each of these pads is normally held up above the die by the slning controlling the arm 2, mounted loosely upon the shaft L, having the bifurcated arms l, each bifureated arm engaging with a pin Z" on either side of the stems b2, c, fil, and c of the knock-out pad. Each bifui-cated arm t is provided with a pin Z5, adapted to be moved down by the projection t, fast on the shaft L, which shaft is operated by the cam (1i-3 and roll y, mounted on the shaft 0 and connecting' with the said shaft L by the arms gm, g, and gli. The purpose of this is to depress the pads when the conveyor moves the blanks from one die to another.

'YV hen the punches descend upon the dies, the

pads are of course depressed by the said punches, and to facilitate the return movement to knock or lift the blank out of the die a piece of soft compressible rubber, as Z7, is used on the second and third die. On the lirst and fourth die the spring Z is sullicient to obtain the proper result. l he two pieces of rubber 7 are suitably mounted, as on the bracket 8, carried by the rod Z, attached to the framework.

rl`he die B is provided with an outer stationary ring or member 63, having an annular ledge b, and an inner ring having an annular liange l, which ring b* is splitinto four parts in a well-known manner and adapted to be expanded by the member operated by the bifurcated arm 1 engaging with the pins 11, carried by the shaft L, which latter isoperated from the cam (ur'l through suitable connections, as the roll y, mounted on the shaft y, arm y, connecting-rod g1, and lever gw. ln this instance the pad is made to serve in conjunction with the split ring /f to pinch the blank against the inner wall of the outer ring so that only the extreme lower edge of the blank will be inwardly curled. Thus the an-. nular flange makes the split ring of the same diameter as the pad when it is expanded, which is equal to the inside diameter of the ring 3. The curling takes place at the peint b1", where there is located the annular ledge 6u, over which the iiange bm of the split ring projects. 1f the blank is not held tightly except at the point where it is to be curled, the effect would be a long sloping' curve instead of a short slight curve at the lower-most edge of the brim of the blank.

lhe die C is composed of an enter ring c3 IOO IIO

and an inner movable ring c1 below the pad 0, provided with a projection 012, which extends up through the aperture 011 in the pad c'. 05 and c are two rock-shafts located parallel to each other and connected at one end by the arms 07 and 08 and the link c. c2 carries a projection C10, which extends into the inner ring 01, while c carries two cutters 011 for cutting the two openings in the blank previously referred to. The rock-shafts are held in their normal position by the spring 011, but are rocked toward each other by the plunger 012, carried by the punch C and moving with the same, descending upon the contacting surface 0111. The effect of this is to cause the inner ring c1 to move in the direction of the cutters 011, so that the projection 011" will pinch the blank against the outer ring and also to impart a rocking motion to the cutters, so as to operate the same,thereby cutting the two openings in the brim of the blank.

rlhe die D has an outer vertically-movable ring (Z3, having an inside peripheral surface or incision (Z and a circumferential ledge 2 held normally in position by the pins (Z 1, having each a spring (Z5. The pins (Z1 rest upon the membe'r (Z6, which is operated from the shaft L3 by means of the bifurcated arm Z12 engaging with the pins Z1 on the said member (ZG. The shaft L3 is operated from the cam by means of the roll Q18, mounted on the shaft g1, arm g1, connecting-rod r/20, and lever Q21. The die D is further provided with an intermediate stationary ring (Z1, having a circumferential depression (Z21, and with an inner expansible split ring (ZS, having an annular flange (Z28 and a circumferential groove (Z60 on the lower side of the flange, which split ring is expanded by the member (Z 1, operated from the shaft L by the bifurcated arm Z11 engaging with the pins Z1" in a manner similar to the ring Z1 of the die B. Adjacent to the die D is a movable plate (Z111, traveling in the curved slot (Z11 by means of the pin (Z12 and operated by the bell-crank (Z13, attached to the framework and receiving its motion from the cam Gr by means of the rod (/22, attached to the rock-shaft L of the wire-feed mechanism, the said shaft L receiving its motion from the said cam Gr6 by means of the rods Q23 and f/21. rlhe plate (Z 11 carries two fingers (Z11 and (Z 1, and carries, further, a knife or cutter (Z17 for cutting off the wire. .The wire is fed through the guides @'50 and (Z50. through the cutter (Z 11, over a groove in the finger (Z 15, and in through the opening (Z111 of the die. The finger (Z1'2 extends into the die through the opening (Z22.

The die E is provided with a stationary inner ring e1 and a stationary outer ring e1 and has pivoted adjacent to it on the arm @2a movable portion c, carrying the piece e2, which bends the excess of wire up against the blank. The portion e is operated through the arm @22 by the cam G1. As will be noticed, the

piece e extends into a cut-out e2 of the die and has an arc-shaped surface e, which comes in contact with the excess of wire.

The wire-feed mechanism I comprises two rolls and the lower of which is mounted in stationary bearings and is operated from the eccentric g2, rack Q21, gear 922, having the pawl g2 moving the same. The pawl (122 engages with the ratchet @'2, mounted on the shaft @'3, carrying the roll The shaft @scarries a gear @'1, meshing with a similar gear @'5 on the shaft of the roll rl'. Owing to the pawland-ratchet mechanism, the rolls will have imparted to them an intermittent motion in one direction only, so as to feed the wire, but will not rotate backward. The upper roll Z is mounted on the toggle-joint @'7, controlled by the rigid connection @'9 of the pivoted arm @'11. The upper roll is normally held out of contact with the lower roll by the spring @11 pressing against the pivoted arm @10. @'12 is a slider controlled by the links @13 and @'11, carried by the rock-shaft 12, mounted in stationary bearings and operated from the cam G2 through the crank @'15 and arms g110 and (/31. The slider @'12 carries a dog @'25, pivoted at its center and normally having engagement with the projection @'26 of the arm @'10 by the spring A forward movement of the slider @'12 will cause the toggle @'7 to be straightened out and the upper roll to descend into lcontact with the lower roll and upon the rotation of the rolls to feed the wire between them. The slider @'12 further carries a retractor-dog @111, which by the action of the spring @'17 will normally grip the wire between itself and the piece of steel @'18 and pull back a certain amount of wire upon the return stroke of the slider independently of the feeding-rolls.

The wire-feed mechanism further carries the shaft I2, provided with the safety-dog @'12, which when rocked backward engages with the pin @2 of the dog @'25 and moves the latter out of engagement with the projection @21, so that the roll will not descend upon the roll when the slider @'12 moves forward, thus preventing any wire from being fed. The movement of the dog @'25 whereby it is disengaged from the projection @'2G also moves the retractor dog @'1'j out of operative position through the instrumentality of the pivoted member @'21, connected with the dog@2 by the spring @'22 and engaging with the projection @'23 of the retractor-dog @16 by means of the ledge @'21. Thus when the dog @'25 is disengaged from the projection @'26 and no wire is fed the retractor-dog @'16 is lifted out of its operative position and no wire is pulled back.

The shaft I2 is controlled by the safety-stop O, which comprises .a pivoted lever 0, located adjacent to the die C on the framework and provided with a member 02, adapted to project into the said die if there is no blank in the said die. rlhe lever 0' is connected with the shaft I2 by means of the rod o3 and crank IOO IIO

IIS

04. The shaft l2 carries a second crank o5, conythere is a blank in the die C, however, the entrance of the member o into the die is arrested by the said blank, thereby preventing' the rod o from rocking the shaft l, and the movement of the cam Gi will then have the effect of merely compressing' the spring' o" without operating the shaft 12 and the safety dog il", mounted on theisame. 1f there is no blank in the die C, the member c is free to enter the same, and the shaft l2 will be rocked by the cam Gr, thus preventing' the wire from being fed to the die D and also preventing' the pull back of the wire. 1f this safety-stop were not provided, the wire would be fed to the die D at all times, and the absence of a blank in the preceding' die to utilize the said wire would result in getting the mechanism tangled up by the unused wire. Several details of construction in the various parts of the machine have been omitted, as they are well known in the art and need not be described elaborately.

The operation of the machine is as follows: The blanks N are fed on the dial H, which revolves continuously and delivers them up to the conveyer J. Before reaching the said conveyer, however, the blanks are detained singly by the action of the stops f and 7:@ lf the conveyer J is now on the back stroke in a longitudinal direction, the strip of metal lifts the stop /r up, and as the opposed gripping portions j and jl of the con veyermove toward each other or toward the center of the path of progression of the blank and clasp the blank the arm jg of the said conveyer engages with the arm 7151 and moves the stop up so that the first pair of opposed gripping portions are allowed to move the blank by its longitudinal forward stroke over on the first die B. As the conveyer J moves forward long'itudinally the stops L and /c drop down -again and prevent the blanks on the dial from being' fed into the? path of progression until the said conveyer returns. As the conveyer moves forward longitudinally the pad B' is depressed by the cam G3, as previously explained, out of the way of the blank, but rises again as the conveyer comes to the end of its stroke to receive the blank. The opposed g'ripping' portions]3 andy'AL now move away from each other or away from the center of the path of progression, leaving' the blank lupon the pad At this moment the punch B descends and the inner split ring If is expanded by the cam G, thereby holding the blank rigid by means of the said split ring and the pad, except at the bottom, whereby the lower edge of the brim a' of the blank is inwardly curled just slightly, as shown in Fig. 6 and Fig. 7, by the circumferential ledge 0u. By the action of the spring the pad nieves out again, carrying the blank with it. ,ln the meantime the conveyer J has moved the length of its return longitudinal stroke, and the opposed gripping lportions ,7'3 and 7"1 now move toward each other again and the second pair of these said opposed gripping portions clasps the blank and carries it to the dies C, the pads and c', as well as the other pads, being' depressed by the cam (ni-3 while another blank is taken from the dial and brought into position on the die B. rl`hepad d rises again and the punch C descends and with it the plunger c", the punch C moving' the blank down on the die and the pluuger cl2 contacting' with the contacting' surface c, thereby moving' the inner ring c against the blank and pinching the'same by means of the projection cu against the outer ring c3, and thereby also operating the cutters c, cutting' the two openings n2 in the blank, as shown in Fig. 8. Incidentally the key impression n" is also made in the blank in this die. The blank is then conveyed to the die D by the next pair of opposed gripping portions in the same manner as previously described, the pads being again depressed at this moment, as previously described. Before the said blank reaches the die D the outer ring d is moved up by the cam G5 in the manner described, thereby bringing into operating' position the inside surface di of the said ring, against which thc wirefeed mechanism l feeds an ex? cess of wire. The split ring Z8 now moves into its expanded position, so that the flange di projects over the circumferential depression Z2? by the cam G", whereupon a very slight movement of the plate Z l takes place,

so that the free end of the wire will be pinched by the iingcr Zw in the groove (Zw and depression ll and so as also to move the other end away from the inner surface (Z by the finger (Zw. At this moment the pull-back device of the wire mechanism is operated and the wire is tightened against the inner split ring (ZS in the groove elm and into the depression (ZW, the outer ring (Z3 moving' down as the surface (X25 is no longer needed. The cam Gr now moves the plate dioutwa1'd,"thus cutting' the wire by means of the cutter d 17 and also bending outward the free end of the wire against the edge of the die. The blank now comes in position on the die outside of the wire, the free end or excess of which projects out through one of the opening'sv/f. The plunger D now descends, forcing' the cover down in the die and the lower edge of the brim into the circumferential depression ([27 of the intermediate ring (Z7, which is now closed by the flange d2, thereby inwardly curling the said brim fa IOO IIO

completely over the wire. 10.) It will be understood that the succession of movements is so rapid that all this is practically accomplished simultaneously. 'Ihe wire is fed against the outer member Z3 instead of into the depression CX27, as it is more easy to do so and to prevent the buckling and bending of the wire. If there is no blank in the preceding' die C, the safety-stop O will act in the manner described and will prevent any wire from being fed to the die I). The blank is then moved to the last die E, where as the punch E descends the piece c7, operated by the cam G7, bends the excess of wire or the projecting strand of wire a3 up against the outside of the brim n of the blank, as shown in Fig. ll. rIhe further advance of the blank brings it upon the chute ew, whereby it is moved out of the machine and disposed of in some suitable way. The dies operate simultaneously, and there is of cou rse always a blank in each die unless by inadvertence the blanks are not fed properly. The blanks are struck up on another press and are fed to the machine in the form shown in Fig. -thatis, provided with a brim a. This is done merely for convenience sake, as another die could of course be had whereby a fiat blank could be acted upon. The openings a2 are cut in the cover in the die immediately preceding the wiring-die, as great care must be taken to convey the said cover in the same relative position, so that the excess of wire will come in alinement with one of said openings n2.

In the present instance a round cover or blank is shown; but any shape of cover could be operated upon. rIhe words ringg "circumferential, Sac.. used in the claims should be construed accordingly.

Instead of having the outer member Z3 of the wiring-die movable it could be made stationary and provided with a groove against which the wire could be fed. The cuttingl mechanism and means for operating the inner movable member of the die C could be operated by cams and slides or by other means in place of the rock-shafts.
